Service is top notch here. It's casual but they take really good care of you. To the point where your iced tea would have tea ice cubes so when it melts, it won't water down your tea! Their iced tea is really good too by the way.
I've had their breakfast/brunch buffet and afternoon tea here. The buffet definitely is a better value compared to the tea service. Although, the buffet is small compared to all the buffets on the strip, the quality is better. Where else can you make/get fresh peanut butter? The buffet is $40 and afternoon tea is $35 per person.
Afternoon tea was good but I enjoyed tea at Mandarin Oriental and Bellagio (Petrossian Bar) more.
In case you are wondering like I was before I went... if you are staying at the Mandalay Bay or Delano, you can charge your expenses here to your room. And the answer is YES if you are wondering about comps too.
